Abstract: Extracts of stem of Niebuhria apetala Dunn was assessed for its antioxidant activity by in vitro methods. Antioxidant activity was studied using 1, 1- Diphenyl-2-Picrylhydrazyl (DPPH), Superoxide scavenging activity, Hydroxyl scavenging activity, ABTS radical scavenging and reducing power assay. Antioxidant activities compared with ascorbic acid as standard antioxidant. Results showed that the crude extracts exhibited significant DPPH, superoxide, hydroxyl, ABTS and reducing power assay. From results, it is concluded that the ethanol extract is the most potent antioxidant. This holds great promise for the use as a source of strong antioxidant compounds.
